At this link here there is a explanation of the shapecfg command. I have finally got everything to work except for the following:
Then you need to configure the shaper0 interface for networking, using the usual sort of ifconfig and route commands.
ifconfig shaper0 host netmask mask broadcast bcast up
route add -net net netmask mask dev shaper0
&
route delete default eth0
route add default gw gateway shaper0
In the above two quotes, the words in italics are to be substituted with the existing values for the ethX card that I want to apply the shapecfg command to. (in my case it it eth2). How do I found out what those values are for ethX on my current working (& un'shaped') system? Yes I looked at the man pages for ifconfig & it was just as cryptic & unhelpful (read I had more questions after I looked at it) as every other man page I have seen. TIA
